Abstract

The prebiotic potential of exopolysaccharide (r-EPS) structures released from Lactobacillus delbrueckii ssp. bulgaricus SRFM-1 was assessed using in vitro fermentations. Fermentations with pure cultures of Lactobacillus (nine strains) and a Streptococcus strain as well as two food-borne pathogenic Escherichia coli were performed. Scanning electron microscopy and Congo red testing revealed that the three r-EPS fractions had different individual structures. All r-EPS fractions were found to stimulate the growth of the lactobacilli and the Streptococcus strain and inhibit the growth of the E. coli strains. Additionally, the primary structure including molecular weight, monosaccharide composition and glycosidic linkages and the individual structures of three r-EPS fractions were found to influence the μmax and cell density of these strains. The results strengthen previous studies on the r-EPS from L. delbrueckii ssp. bulgaricus SRFM-1 and provide additional validation of r-EPS as a potentially novel prebiotic for incorporation in functional foods.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
